C4L v Cup

The C4 Leichtbau’s build strategy was the polar opposite of its nearest sibling the 1990 Carrera Cup car. While Roland Kussmaul built the Carrera Cup car by stripping down a Carrera 2, Jurgen Barth built the C4 Leichtbau by building up a Carrera 4 shell. In the end the cars shared many similarities but also key differences and ironically the Cup car proved a better race car than the purpose built C4 Leichtbau. But the C4 Leichtbau was most certainly the more technologically advanced effort.
